When a person challenges a book, they are attempting to remove or restict access to that book. If they are successful, then the book is banned.
Every year, across the country, books are challenged in schools and libraries for their "inappropriate" content.
Banning books is a challenge to your First Amendment rights and takes away an individual's right to choose material that is appropriate for yourself or your family.
"Celebrate the Freedom to Read" by reading a book from the American Library Association’s (ALA) banned book list.

Over the past ten years, American libraries were faced with 4,660 challenges.
Further, 121 materials were challenged because they were “anti-family,” and an additional 304 were challenged because of their “religious viewpoints.”
1,720 of these challenges (approximately 37%) were in classrooms; 30% (or1,432) were in school libraries; 24% (or 1,119) took place in public libraries. There were 32 challenges to college classes; and 106 to academic libraries. There are isolated cases of challenges to materials made available in or by prisons, special libraries, community groups, and student groups. The majority of challenges were initiated by parents (almost exactly 48%), while patrons and administrators followed behind (10% each).
